T-Mobile connected me to this site as a weekly customer "Thank You". Tried using a coupon that said I had to show my screen. I am not going to the pizza parlour on a Friday night to wait. Called the store and they seemed generally confused and unhelpful. Just one of another coupon site that offers garbage. Steer clear!
Tip for consumers: Don't bother. You can get fake coupon codes on hundreds of other sites.
